First thing first, this is just for demonstration purpose and might *not* be a supported solution by Microsoft. The setting we are reading from are hidden messages and not documented anywhere. I had to reverse engineer it for demonstration purpose. Objective : To get OOF State of any user in your organization. Challenges: You might ask me why not use GetUserOofSettings to query user’s OOF status with the help of Exchange Impersonation? This is due to the limitation of EWS’s GetUserOofSettings/SetUserOofSettings

This is going to be a very simple sample of how you can send an email with custom properties set and also change the message class so that it render on outlook as Custom Form. Prerequisites: A custom form must be published with same class name to render the email properly. How it works… Step 1) It drop an email in the drafts folder of user Step 2) Patches the properties to set Message Class & other properties, even including with special characters in name like Spaces and ‘/’ Step 3) Drop the

What are we doing here? What is Search Folder? Why do I care? Search folders are a quick way to bookmark your frequently searched items. It allows you to save a search query with predefined parameters for quick access. For instance I am always looking for emails with attachments and from a particular sender where the subject has some specific words. Yeah a rule could do that but I want to search in multiple folders and keep the individual mails in their individual folders. Complex? not really! Search

This was a tough one and was lots of learning for me as well. Me and my colleague was working on a customer issue where his intentions were to list all the permissions on Exchange 2003 Mailbox Store. Of course one can go to Exchange System Manager (ESM), but considering an environment with 20+ Exchange server and over 100 Mailbox stores it could be a tedious task to satisfy the Auditing Team. There are tools that can give you that information to some extend like, PFDavAdmin and DSACLS but the information

I thought it was just the last month full of bugs and fixes. This month also started with a Exchange Web Services bug.. or better Exchange Bug as Exchange Web Service is just a victim :( If you add an attachment to a single occurrence of a recurring CalendarItem, and then call GetItem with AllProperties set to retrieve that occurrence, the attachment is returned but HasAttachments property is set to false. Not only that you cannot see the attachment in the OWA, but Outlook has no problem in showing

OK, I’m not exactly the hard-core Windows Mobile developer here. However, I had a recent issue with a customer who wanted to be able to use a PUSH to a windows mobile device which would be in stand-by. Their goal was to save on the battery life. Let’s start off with this: · WM devices support one Exchange server, but multiple POP3. · The devices wake on user action, timer, incoming SMS message or EAS call (not to mention a phone call). · The EAS protocol requires a special license for development.
